Is it even possible to enable the HDR option from within my application? I assumed it would be there automatically. I looked for additional mediaTypes, thinking maybe kUTTypeHDRImage might be an option, but no such luck. It's not an additional source type, nor is it available through cameraCaptureMode.
ipc.sourceType = UIImagePickerControllerSourceTypeCamera;
ipc.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeImage];
No mention of it in the documentation: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIImagePickerController_Class/UIImagePickerController/UIImagePickerController.html
